Re: Update to broken timing chain. If the pistons aren't cracked or significantly damaged, clean up the 'eyebrows' with a small file and/or sandpaper. You don't want any sharp edges or loose material in there. Get the valves replaced and put it back together, and hope it stays together. It should be fine unless you are running nitrous or boost. If that's the case, I'd take this opportunity to build up the bottom end stronger.

Re: Update to broken timing chain. a touch of oil to control shavings and either emory paper or medium scotch brite works well. I personally think that sandpaper is too course. The piston material is far softer than it should be. The primary idea is to remove sharp areas and such that might become hot spots are hang on to coke. One youve smoothed it down a teeny bit just wipe all the (now grey) oil away.
